The position or rank held by a sergeant in a military or police organization.
He was promoted to the sergeancy after years of dedicated service.
Sergeancy is derived from the Old French word 'sergien', meaning a servant or attendant, which in turn comes from the Latin 'serviens' (meaning serving). The suffix '-cy' indicates a state or condition. Thus, 'sergeancy' refers to the state or condition of being a servant or attendant.
Think of 'serving' ('serviens') to remember that 'sergeancy' refers to the state of being a servant or attendant.
